To subtract numbers in scientific notation, the exponents must be the same.
First, rewrite the numbers in scientific notation:
4.4951 X 10^9 = 4495100000
57.9 X 10^7 = 579000000
Since the exponents are not the same, we need to adjust them.
To adjust the exponents, we can move the decimal point in each number until there is a common exponent. So, let's shift the decimal point in 4495100000 by 2 places to the right to align the exponents:
4495100000 = 44.951 X 10^10
Now that the exponents are the same (10), we can subtract the numbers:
44.951 X 10^10 - 579000000 = 44.951 X 10^10 - 5.79 X 10^8
Next, we can subtract the mantissas (the numbers before the exponent):
44.951 - 5.79 = 39.161
Finally, we can write the result in scientific notation:
39.161 X 10^10
So, 4.4951 X 10^9 - 57.9 X 10^7 is equal to 39.161 X 10^10.
4.4951 X 10^9 - 57.9 X 10^7
Step by step in scientific notation.
